In an air gun of the related art, even if it is attempted to independent and separately adjust a firing operation and a blowback operation, this type of independent adjustment is difficult.This problem is solved by an air gun for firing a bullet using compressed gas, and having a mechanism for performing blowback, wherein the blowback mechanism is provided with a firing air chamber25aand a blowback air chamber25b, being two cavities capable of being supplied with compressed gas from a compressed gas source A and being sealed to contain the compressed gas, inside a valve body24, a firing valve27inside the firing air chamber25a, a blowback valve29inside the blowback air chamber25b, and two valves27, 29that are capable of actuation independent of each other by operation of a trigger.
